Good

Liking is a comparision between an already built image in mind and comparing the object against it.
If it passes the comparision its good..otherwise its not
suppose for me a white colored ambassador is a perfect example of car
every car i see ..i would invariably compare with this ..if it matches its a good one
otherwise not...

Thats a reason a thing liked by somebody is not liked by everyone....
as thier mind holds a different image of the object..
until the other object is close to that image ...they will not say yes...or smile.or nod
